[0002] During the operation of industrial equipment, the hydraulic system, as the core power transmission unit, directly affects the system's stability, component lifespan, and overall machine reliability due to the cleanliness of its internal hydraulic fluid. However, after long-term use, maintenance, or replacement of parts, contaminants such as metal shavings, welding slag, dust, moisture, and aged sludge can easily accumulate in the hydraulic circuit. If these contaminants are not thoroughly cleaned before operation, it can lead to valve core jamming, seal wear, pump damage, or even system failure.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-5 This utility model relates to a portable filtration device for cleaning, comprising an oil storage tank 1, a movable platform 2, a cleaning area 3, a pump unit 4, a filter module 5, and a pressure regulating and protection module 6. The oil storage tank 1 is fixedly installed on the upper part of the movable platform 2 and is used to hold hydraulic oil. The cleaning area 3 is located above the front side of the movable platform 2, and has foldable storage plates on both sides. The oil inlet of the pump unit 4 is connected to a suction filter 8 through a pipeline. The oil inlet of the suction filter 8 extends into the oil storage tank 1, and the oil outlet is connected to the oil inlet of the pump unit 4. The oil outlet of the pump unit 4 is connected to the inlet of the filter module 5 through one end of a three-way ball valve 9. The filter module 5 includes a first-stage filter element arranged in series. The first-stage filter element has its outlet connected to the inlet of the second-stage filter element via a pipeline.

The throttle valve 14 is connected in series in the outlet pipeline of the pump group 4. The check valve 15 is located between the outlet of the filter module 5 and the oil supply pipeline of the cleaning area 3. The pressure gauge switch 12 is connected to the pressure detection point at the outlet of the filter module 5 and is connected to the pressure gauge 17.

[0026] The portable filtration device for cleaning provided in this embodiment enables efficient, convenient, and high-cleanliness on-site cleaning of hydraulic systems or equipment. The entire device uses the mobile platform 2 as a carrier platform, organically integrating functional units such as oil storage, oil supply, filtration, pressure regulation protection, and operating areas to form a self-circulating, independently operable cleaning system.

[0027] It should be noted that: the oil storage tank 1, as a storage and sedimentation container for the hydraulic medium, not only provides the oil required for cleaning, but also ensures maintenance convenience and system safety through the bottom drain valve 16 and the top vent valve 10; the level gauge 7 on its side wall facilitates real-time monitoring of the oil level, ensuring stable operation. The pump unit 4 uses the suction filter 8 to initially purify the oil entering the system, effectively preventing impurities from causing wear on the pump body and extending the overall lifespan of the machine. The filter module 5 adopts a two-stage filtration structure, intercepting contaminants of different particle sizes at each stage, ensuring that the oil output to the cleaning nozzle reaches a high level of cleanliness, meeting the cleaning requirements of precision equipment. The pressure regulation and protection module 6, through the coordinated action of the safety valve 11, throttle valve 14, check valve 15, and pressure gauge switch 12, achieves dynamic adjustment of system pressure, overload protection, flow control, and visual monitoring of pressure status, thereby ensuring the safety and controllability of equipment operation while guaranteeing the cleaning effect. In non-cleaning conditions, the oil can be directly returned to the oil tank through the three-way ball valve 9, avoiding unnecessary energy consumption and filter element wear. In addition, the cleaning area 3 is equipped with a foldable storage board and a combined oil supply line, which takes into account both the flexibility of the operating space and the pressure resistance and reliability of the pipeline; while the mobile platform 2 has braked casters at the bottom, which improves the overall mobility and positioning stability of the machine, making it suitable for a variety of working environments.

[0028] Specifically, the pressure gauge switch 12 is a needle valve type, with one end connected to the outlet pipe of the filter module 5 via a threaded connector, and the other end connected to the pressure gauge 17 via a compression fitting; the oil storage tank 1 is equipped with an exhaust valve 10 at the top, a level gauge 7 on the side wall, and an oil drain valve 16 at the bottom; the third port of the three-way ball valve 9 is connected to the upper oil return port of the oil storage tank 1 via a return oil pipe, which is located upstream of the throttle valve 14.

[0029] Furthermore, the bottom of the mobile platform 2 is equipped with four universal wheels with braking function, and the front, left and right sides and top of the oil storage tank 1 are equipped with openable door panels, wherein an oil suction filter 8 is installed on the inner side of the left door panel; the drive motor of the pump group 4 is fixed on the inner bottom plate of the mobile platform 2 and connected to the pump body input shaft of the pump group 4 through a coupling; the oil supply pipe of the cleaning area 3 is composed of a combination of stainless steel rigid pipe and high-pressure hose, wherein the rigid pipe section is fixed to the inner side of the column of the mobile platform 2, and the hose section is connected to the cleaning nozzle.

[0030] The operation process of this embodiment is as follows: First, move the device to the vicinity of the equipment to be cleaned using the universal wheels with brakes at the bottom, and press the brake to fix the position to ensure the stability of the whole machine during operation; then, open the openable door panel on the top or side of the oil storage tank 1, check whether the hydraulic oil level in the tank is within the normal range shown by the level gauge 7, and if the oil level is insufficient, add oil to the specified height, and confirm that the exhaust valve 10 is in the open state to remove air from the system; next, unfold the foldable storage plates on both sides of the cleaning area 3 to facilitate the placement of the parts or tools to be cleaned; before starting, operate the three-way ball valve 9 to connect the outlet of the pump group 4 with the filter module 5, close the return oil bypass, and at the same time confirm that the hand valve 13 is in the closed state; then start the drive motor of the pump group 4, and the hydraulic oil enters the pump group 4 after preliminary filtration by the suction filter 8, and is pressurized and output by the pump; the high-pressure oil flows through the throttle valve 14 for initial flow adjustment, and then achieves overpressure protection through the threshold set by the safety valve 11, and then flows through the first stage and the second stage in sequence. The secondary filter element completes deep purification; the purified clean oil is prevented from flowing back through the one-way valve 15 and is transported to the cleaning nozzle through the oil supply pipeline composed of stainless steel rigid pipe and high-pressure hose; at this time, slowly open the hand valve 13, adjust the required cleaning pressure, and use the hand nozzle to rinse the target area; during the cleaning process, the pressure gauge 17 can be controlled by the pressure gauge switch 12 to monitor the outlet pressure of the filter module 5 in real time and determine whether the filter element is blocked or the system is abnormal; if self-cleaning or preheating of the oil is required, the three-way ball valve 9 can be switched to the return oil position so that the oil returns directly to the oil storage tank 1 without passing through the cleaning nozzle, forming an internal circulation; after cleaning, first close the hand valve 13 to stop spraying, then turn off the pump group 4 motor, and close the exhaust valve 10 after the system pressure is released; finally, open the drain valve 16 at the bottom of the oil tank to drain the waste oil for replacement, or to maintain and repair components such as the suction filter 8 and filter element; finally, put away the storage plate, release the brake, and the whole machine can be moved away from the site.
